Definitions

  • a continuously porous synthetic resin layer having numerous macropores is provided on the surface of a substrate, the synthetic resin layer being compressed to a thickness of not greater than 70% of the original thickness with application of heat so as to deform the macropores to depressed pores, while being rendered smoothsurfaced or provided with a pattern-embossed smooth surface, if desired, the layer being -nished by further coating, and the lining for shoes thus obtained is satisfactory in air permeability, moisture permeability, water absorption and has a smooth surface and excellent touch.
  • horsehides, pigskin and thelike have been used as suitable lining materials for shoes because of their attractive appearance and moderate smoothness of the surface, moisture permeability, water absorption, air permeability, agreeable touch and high strength.
  • yMost of the synthetic leathers heretofore produced for linings were produced by applying a synthetic resin solution to the surface of a substrate such as woven fabric and drying the resultant coating, or by joining a sheetlike resin layer to a substrate, and the products obtained were finished by pattern embossing, dyeing or the like in order to provide them with leather-like surfaces.
  • the synthetic resin layer has a line structure
  • such synthetic leathers are extremely poor in properties such as moisture permeability and water absorption which are essential to linings for shoes.
  • the woven fabric gets frayed at the cut end to impair the appearance and quality of the shoes.
  • a non-Woven fabric as the substrate and form thereon a synthetic resin layer which insures moisture permeability and water absorption so as to obtain a substitute which is similar to natural leather in appearance, touch and strength.
  • moisture permeability and water absorption are generally provided by subjecting a synthetic resin solution to wet coagulation to form a microporous synthetic resin layer, but where a non-woven fabric vcoated with a synthetic resin solution is merely subjected to wet coagulation, the rough-surfaced non-woven fabric having uneven coarseness makes it diflicult to permit uniform permeation of the synthetic resin solution into the fabric, with the result that the surface smoothness of the resin layer is impaired. Being low in neness, the resin layer has poor resistance to abrasion.
  • the present invention relates to linings for shoes made of synthetic leather and a method for producing the same, the synthetic leather provided by this invention being composed of a substrate and a porous synthetic resin layer formed thereon which has a smooth and lustrous surface, excellent moisture permeability, water absorption and abrasion resistance.
  • a synthetic resin solution is directly applied to the surface of a substrate and the substrate thus coated is then immersed in an aqueous coagulating solution for coagulation, whereby the substrate is covered With a continuously porous synthetic resin layer having a great number of macropores.
  • the present method produces a synthetic resin layer in the form of porous construction incorporating both micropores and numerous macropores by using a synthetic resin solution which contains a watersoluble pore forming agent or an exceedingly great amount of solvent.
  • the product thus obtained is not fit for use as a shoe lining, because although sufficient in moisture permeability and water absorption it is not satisfactory in surface smoothness and Wear resistance and has a ruberlike touch without moderate stiffness. Accordingly, the above porous synthetic resin laminate is then subjected to extreme pressure from the surface of the resin layer to effect plastic deformation, whereby the vicinity of the surface area is compressed into a layer of fine texture with resultant advantages of improved abrasion resistance and smoothness of the surface.
  • the provision of the original thick, porous synthetic resin layer results in smooth-surfaced laminate n spite of the rough surface of the substrate, assuring satisfactory appearance well-lit for use as a synthetic leather for linings. Numerous pores still present in the interior of the synthetic resin layer, though deformed into flat shape by the compression, afford sufficient moisture permeability and water absorption.
  • macropores are deformed into depressed pores with varying degree of tlatness depending upon the roughness of the substrate surface serves to obtain a smooth-surfaced synthetic resin layer While, despite compression, good air permeability is achieved due to the presence of the residual depressed pores. If compression is effected after provision of a porous resin layer including only micropores, the pores will be eliminated to result in little or no air permeability, whereas the present invention is free of such defect.
  • the use of a hot roll or hot plate engraved with a natural leather-like pattern during the foregoing compression deformation produces an embossed surface resembling the surface of a natural leather and surface coating may further be provided to enhance attractive appearance and luster, strength and smoothness of the surface.
  • the lining for shoes produced has outstanding moisture permeability and water absorption.
  • the surface of the lining has -a fine texture, satisfactory smoothness and abrasion resistance, with improved luster and smoothness insured by the surface finishing.
  • the interior structure of the laminate which, in its entirety, gradually increases in neness from the substrate side toward the porous resin surface resembles that of the natural leather, thus imparting a natural leather-like touch.
  • An object of the present invention is to provide a synthetic leather which has staisfactory smoothness, luster, moisture permeability, Water absorption and natural leather-like touch which are required for shoe linings to be brought into frictional contact with the sides and heel of the foot all the time.
  • Another object of the present invention is to provide a lining for shoes made of a synthetic leather comprising a thin porous synthetic resin layer which is excellent in moisture permeability, water absorption and smoothness and which can be readily provided with a pattern-embossed smooth surface.
  • Still another object of the present invention is to provide a method for producing, with ease and at low cost, an excellent synthetic leather well-suited for lining for shoes.
  • FIG. 1 is an enlarged view in vertical section of a lining material before it is subjected to compression forming; and FIG. 2 is an enlarged view in vertical section of a finished lining material obtained Iby compression forming.
  • a coating solution prepared by adding a suitable amount of a pore forming agent such as polyethylene glycol, a water-soluble inorganic salt or the like to a synthetic resin solution such as a dimethylformamide solution of polyurethane is applied to the surface of a substrate such as a woven fabric or non-woven fabric is a suitable thickness by roller coating, knife coating or the like.
  • the substrate thus coated with the above solution is immersed in yan aqueous coagulating solution for the wet coagulation of the above synthetic resin solution layer.
  • the synthetic resin solvent e.g. dimethylformamide
  • the water-soluble pore forming agent e.g.
  • polyethylene glycol or neutral, water-soluble inorganic salt is extracted into the aqueous coagulating solution, whereby upon coagulation of the synthetic resin (such as polyurethane) a continuously porous synthetic resin layer incorporating numerous macropores 2 as shown in FIG. .1 is formed on one surface of the substrate 1.
  • synthetic resin such as polyurethane
  • the porous layer may suitably be 0.1 to 0.8 mm., preferably 0.2 to 0.5 mm. in thickness.
  • the size (i.e. diameter) of the macropores 2 to be formed in the porous layer is preferably 20 to 70%, most preferably 30 to 60%, of the thickness of the porous layer. The size exceeding 70% is not desirable since it is detrimental to the smoothness of surface of the porous layer.
  • porous laminate The laminate thus comprising the substrate 1 and the porous layer formed on the surface thereof (which is hereinafter referred to as porous laminate) is then washed with water to remove the solvent and pore forming agent and dried.
  • the porous laminate thus obtained namely the lining material comprising the porous synthetic resin layer 3 and the substrate 1 is subjected to hot compression from above so as to materially compress the porous synthetic resin layer 3 against the substrate to a thickness of not more than about 70%, preferably of about 5 0 to 60% of the original thickness.
  • excess compression must be avoided since the pores will be apt to be crushed and eliminated.
  • macropores 2 are deformed into thin Hat pores 2' having a small thickness and relatively large dimensions in the directions parallel to the surface of the porous synthetic resin layer 3, while the layer is rendered perfectly smoothsurfaced or provided with a pattern-embossed, substantially smooth surface.
  • the depressed pores thus deformed have a transverse dimension of 20 to 50% of the thickness of the synthetic resin layer, the ratio of the transverse dimension to the longitudinal dimension being about 1:1.2 to l:1.6.
  • the smooth surface to be provided on the porous synthetic resin layer during the hot compression is formed by means of a smooth-surfaced roller, while a substantially smooth, pattern-embossed surface is produced by an ernbossed roller.
  • the hot compression is preferably conducted at a temperature of to 180 C. most preferably at 130 to C.
  • the lining material thus obtained by extreme compression of the relatively thick, porous, synthetic resin layer 3 has a very smooth surface and fine texture in spite of the rough surface of the substrate 1. Since numerous macropores 2 in the interior are compressed, a considerable number of the macropores 2, even when subjected to extreme compression, are still retained in the porous synthetic resin layer in the form of deformed, depressed pores 2 which provide excellent moisture permeability,
  • substrate as herein referred to includes woven fabrics, non-woven fabrics and the like.
  • non-woven fabrics are a non-Woven fabric obtained by needle-locking a fiber web (batt) and a non-woven fabric obtained by needle-locking a ber web (batt) and then impregnating theresulting fabric with synthetic rubber, synthetic resin or the like.
  • Suitable synthetic resins for forming the porous synthetic resin layer 3 include, for example, polyurethane, polyvinyl chloride, polyamide and the like, the most preferable being polyurethane.
  • polyurethane a material obtained by reacting polyisocyanate with polyester diol or polyalkylene glycol ether and chain-extending the resultant prepolymer with a compound having at least two active hydrogen atoms.

  • solvent for the synthetic resin such as polyurethane'are N,N-dimethylformamide, N,N-dimethylacetamide, tetrahydrofuran, dimethyl sulfoxide, etc.
  • Suitable water-soluble, pore forming agents to be used in the present invention are polyethylene glycols and water-soluble inorganic salts, the preferable polyethylene glycols being those having an average molecular weight of 200 to 2,000.
  • desirable water-soluble inorganic salts are sodium chloride, sodium sulfate, ammonium sulfate etc.
  • the water-soluble pore-forming agent may be used preferably in an amount of 10 to 200% (by weight), most preferably of 20 to 150% (by weight) based upon the weight of the synthetic resin contained in the synthetic resin solution (i.e. the foregoing coating solution).
  • aqueous coagulating solution (bath) are water, aqueous solutions vof the above water-soluble inorganic salts.
  • the laminate was then pressed by a kid-pattern embossed roller (clearance: 0.4 mm.) heated to 140 C., with the result that a laminate having a thickness of 0.9 mm. was obtained.
